A QUEENSLAND couple is hoping to be the first to tie the knot while diving underwater with great white sharks at Neptune Islands.
A couple has enquired with local shark cage dive company Calypso Star Charters to say "I do" when they dive with the great whites in December.
Natasha Becker from Calypso Star Charters said the company was now searching for a celebrant to perform the ceremony.
She said it was the first time anyone had asked to be married in the cage.
"We've had engagements, but this is our first wedding," she said.
"Now we are trying to find a celebrant."
Ms Becker said because the company's boat was equipped with face communication masks, the couple would be able to talk to each other while in the cage underwater.
"They would be able to actually talk to one another during the dive," she said.
"If they are (a celebrant) interested, certainly get in touch with us.
"We can get the contact details of the couple and put the information forward to try to make it happen."
Ms Becker said if the wedding went ahead, other guests aboard the charter on that day would also be able to watch the action from two underwater cameras on the cage that send video back to televisions on board the boat.
She said there would be no shortage of room in the shark cage, which is built to hold eight people but usually has six people diving at any one time.
If you know a celebrant interested in taking the dive, contact Ms Becker on 8682 3939.
